BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap in which a lid is hingedly connected to a cap body, and more particularly to a one-touch cap which can easily open the lid.

[0002]

2. Description of the Related Art An elastic body made of an elastomer or the like is provided between a cap body and a lid, and the lid is urged in the opening direction by the elastic body. In some cases, the opening operation of the lid is made quick.

In the cap, when the lid is closed, the engaging portion of the cap body and the engaging portion of the lid engage with each other,
Further, a stopper plug of the lid is fitted into the pouring hole of the cap body. Therefore, in order to open the lid, it is necessary to release the engagement and the fitting, and for that purpose, it is necessary to push up the front end portion of the lid with a finger.

[0004]

However, the operation required when the lid is opened in the above-mentioned conventional cap, that is, the operation of pushing up the lid with a finger belongs to the complicated operation of the finger, and the operability is very good. Not a thing.

[0005] The present invention has been made in view of such problems of the prior art, and an object of the present invention is to provide a cap having a simple structure and good operability in opening a lid.

[0006]

The present invention has the following features to attain the object mentioned above. <Summary of the present invention> The present invention provides that an engagement cylinder portion that engages with the mouthpiece portion of the container extends from substantially the center of the top plate portion of the cap body,
A cosmetic tube portion surrounding the engagement tube portion extends downward from the outer peripheral edge of the top plate portion, and an ejection hole is provided in the top plate portion inside the engagement tube portion,
A lid is rotatably provided at the rear end of the top plate via a hinge, and the lid is urged in an opening direction by an elastic body provided between the lid and the cap body. In a cap provided with a closing plug that protrudes into the pouring hole, the upper front portion of the decorative tube portion and the top plate portion are separated by a groove provided therebetween, and the front portion of the decorative tube portion is The operating portion is elastically pushable inward, and an engaging portion that can be engaged and disengaged from each other is provided substantially at the upper center of the operating portion and at the lower front portion of the lid. A concave portion that is recessed toward the rear side of the cap body is provided in the top plate portion of the portion facing the joint portion, and a push-up arm that projects toward the concave portion is provided behind the engaging portion of the operation unit. When the operation unit is pushed inward, it is guided by the edge of the recess and flexes obliquely upward. A cap, characterized in that push up the lid projecting lid side while (corresponding to claim 1).

Hereinafter, the points of the present invention will be briefly described. Generally, the cap body and the lid are integrally formed of plastic. However, it is also possible to form the cap body and the lid body separately and connect them with a hinge member.

[0008] The engagement means between the mouth tube portion and the engagement tube portion of the container,
Any means such as screw connection or fitting connection may be used.
The elastic body for urging the lid in the opening direction can be formed of an elastomer, rubber, or the like.

The operating portion and the engaging portion provided on the lid engage with each other when the lid is closed, hold the lid in a closed state against the urging force of the elastic body, and hold the operating portion inward. Any shape may be used as long as it has a function of releasing the engagement when pushed in.

The recess provided in the top plate does not hinder the rearward movement of the push-up arm when the operating section is pushed inward, and
The shape and size of the push-up arm are not particularly limited as long as it has a function of guiding the push-up arm to bend obliquely upward.

If the push-up arm has a function of being guided by the concave portion of the top plate portion when it is pushed in and elastically bent obliquely upward and protruding toward the lid, the push-up arm has a function of pushing up the lid.
Any shape and size may be used, but it is preferable to make the shape and the size substantially close the recess so that the appearance when the lid is opened is good.

Preferably, a thin hinge portion is provided between the operating portion and the push-up arm (corresponding to claim 2).
When the thin hinge portion is provided in this manner, the push-up arm bends obliquely upward smoothly.

It is preferable that the lid is provided with a projecting piece against which the tip of the push-up arm abuts (corresponding to claim 3). When the projection is provided on the lid as described above, the protrusion of the push-up arm required for releasing the fitting between the stopper of the lid and the ejection hole of the cap body can be reduced.

[0014] (corresponding to claim 4) the thickness of the operation portion, is preferably thinner than the thickness of other cosmetic tubular portion.
When the thickness of the operation unit is reduced as described above, the operation unit is easily pushed inward.

<Raw Materials of the Present Invention> Examples of the material of the cap body and the lid in the cap of the present invention include plastics such as polypropylene and polyethylene.

[0016]

[Action] <Action of the present invention> In the closed state of the lid,
The engaging part of the operating part and the engaging part of the lid are engaged, and the stopper of the lid is closely fitted to the pouring hole of the cap body. By these engagement and fitting, the lid is held in the closed state against the urging force of the elastic body.

When the operating portion of the cap body is pushed inward in the closed state of the lid, the engagement between the engaging portion of the operating portion and the engaging portion of the lid is released. The lid is guided obliquely upward by the concave portion of the plate portion and moves forward, and the tip protrudes toward the lid to lift the lid, whereby the stopper plug comes out of the pouring hole.

As a result, the lid released from the cap body is opened by the urging force of the elastic body, and is fully opened. When the force for pushing the operation section inward is removed, the operation section returns to its original state by its own elasticity, and the push-up arm is also pulled back forward to return to its original form.

When the lid is closed, the lid is rotated downward and pressed against the cap body, so that the engaging portion of the lid is engaged with the engaging portion of the cap body, and the stopper is closed. Fits tightly in the hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. [First Embodiment] FIG. 1 is an external perspective view of a cap according to a first embodiment of the present invention, and FIG. 2 is a longitudinal sectional view thereof.

The cap includes a cap body 10 and a lid 30 integrally formed of resin, and an elastic body 50 for urging the lid 30 in the opening direction. Cap body 10
Has a structure in which the engagement cylinder 12 and the decorative cylinder 13 are connected by the top plate 11. That is, from the center of the top plate portion 11, an engagement cylinder portion 12 having a female screw portion 12a on the inner peripheral surface and screwing to a mouth cylinder portion (not shown) of the container extends downward.
A decorative tube 13 surrounding the engagement tube 12 extends downward from the outer periphery of the top plate 11. A spout hole 14 is opened in the top plate portion 11 inside the engagement tube portion 12, and when the cap is mounted on the mouth tube portion of the container, the contents in the container are removed from the spout hole 14. It can be poured out.

A lid 30 is rotatably connected to the rear end of the cap body 10 via a pair of thin hinge portions 15. The lid 30 has a top plate portion 31 and a peripheral wall portion 32, and a cylindrical stopper plug 33 that can be fitted into the pouring hole 14 is provided at the center of the top plate portion 31. The peripheral wall portion 32 contacts the upper edge of the decorative tube portion 13 when the lid is closed.

The elastic body 50 is formed of an elastomer, and has a substantially U-shaped cross section before elastic deformation. One end 51 of the elastic body 50 is inserted into a mounting hole 16 provided at the rear of the top plate 11 of the cap body 10 and near the thin hinge 15, and provided on the outer peripheral surface of the engagement cylinder 12. It is hooked on the hook 12b.

The other end 52 of the elastic body 50 is arranged along the peripheral wall 32 of the lid 30 when the lid 30 is open as shown in FIG. When the lid 50 is closed, the central portion 53 of the elastic body 50 is elastically bent as shown in FIG. 2, and the other end 52 of the elastic body 50 comes into contact with the top plate 31 of the lid 30. . The lid 30 is biased in the opening direction when the lid is closed by the elastic force of the elastic body 50.

The front portion of the decorative tube portion 13 is made thinner than the other portions of the decorative tube portion 13, and this thin portion serves as the operation unit 20. A slot 21 for separating the upper edge of the operation unit 20 from the top plate 11 is formed between the upper part of the operation unit 20 and the top plate 11.
Can be elastically pushed inward and deformed.

A recess 17 is formed in the center of the front portion of the top plate 11 of the cap body 10 so as to be recessed rearward and reach the outer peripheral edge of the engagement cylinder portion 12. The recess 17 is continuous with the slot 21, and the rear end of the recess 17 is a tapered surface (edge) 17 a.

In the center of the upper part of the operation unit 20, there is provided an upright part 22 which rises after being slightly retracted rearward.
An engagement protrusion (engaging portion) 23 is provided in front of the upper edge of the upright portion 22, and a push-up arm 24 is provided in rear of the upper edge of the upright portion 22.

The upper edge of the upright portion 22 and the upper edge of the base of the push-up arm 24 are connected by a thin hinge portion 25. The push-up arm 24 has a flat plate shape, and the upper surface thereof is flush with the upper surface of the top plate 11. The lateral width of the push-up arm 24 is slightly smaller than the lateral width of the concave portion 17 of the top plate portion 11, and the leading end 24 a of the push-up arm 24 extending rearward is a tapered surface that comes into contact with the tapered surface 17 a of the concave portion 17. . The recess 17 is substantially closed by the push-up arm 24.

When the operating portion 20 is pushed inward, the tip portion 24a of the push-up arm 24 slides on the tapered surface 17a of the concave portion 17 and is guided obliquely upward, whereby the thin hinge portion 25 is elastically bent. I do. As a result, the push-up arm 24 is pushed up obliquely upward, and the tip portion 24a projects beyond the upper surface of the top plate portion 11.

A pair of projecting pieces 34 are provided at the center of the front portion of the top plate 31 of the lid 30. The tip of the protruding piece 34
As shown in FIG. 2, when the lid is closed, the top plate portion 11 of the cap body 10 and the top surface of the push-up arm 24 are located slightly apart from each other, and are positioned so as to straddle the top plate portion 11 and the push-up arm 24. I have.

Therefore, when the operating section 20 is pushed inward and the push-up arm 24 is pushed up obliquely upward, the tip of the push-up arm 24 hits the projecting piece 34 and pushes up the lid 30.

An engaging projection (engaging portion) 35 is provided on the lower edge of the front center of the peripheral wall portion 32 of the lid 30 so as to project inward. When the lid is closed, the engagement projection 35 is
0 engages with the engagement projection 23 of the operation unit 20.

<Covered state> With this cap, when the cover is closed,
As shown in FIG. 2, the lower edge of the peripheral wall portion 32 of the lid 30 abuts on the upper edge of the decorative tube portion 13 of the cap body 10, and the operating portion 2
0 engagement projection 23 engages with engagement projection 35 of lid 30,
The tip of the closure plug 33 of the lid 30 fits tightly into the pouring hole 14 of the cap body 10 to seal the pouring hole 14.

When the lid is closed, the elastic body 50 is in an elastically deformed state, and the elastic body 50 urges the lid 30 in the opening direction. Further, the fitting force between the stopper plug 33 and the pouring hole 14 is larger than the elastic body 50.
Is larger than the elastic force, the lid 30 is held in the closed state.

<Opening Operation> When opening the lid 20 of the cap, a thumb is attached to the operating section 20 of the cap body 10,
A finger other than the thumb is applied to the rear portion of the cap body 10 and the operation unit 20 is pushed inward.

Then, first, the engagement protrusion 23 of the operation portion 20
And the engagement projection 35 of the lid 30 is released. At the same time, the tip portion 24a of the push-up arm 24 slides on the tapered surface 17a of the concave portion 17 to advance obliquely upward, and accordingly the thin hinge portion 25 elastically bends and pushes up the push-up arm 24 obliquely upward. The tip portion 24a of the push-up arm 24 protrudes above the top plate portion 11.

Then, the pushed up arm 2
After the engagement between the engagement protrusion 23 and the engagement protrusion 35 is released, the front end 24a of the fourth member abuts on the protrusion 34 of the cover 30 and pushes the cover 30 upward. As a result, the stopper 3
3 is pulled out from the pouring hole 14 and the fitting between them is released.

Since the protruding piece 34 is located near the fitting portion between the stopper plug 33 and the pouring hole 14, the force for lifting the lid 30 is applied to the fitting between the stopper plug 33 and the pouring hole 14. It can act very effectively as a releasing force.

The engagement between the engagement portions 23 and 35 and the closing plug 3
When the fitting between the nozzle 3 and the pouring hole 14 is released, the lid 30 is vigorously rotated in the opening direction by the elastic force of the elastic body 50, and becomes a fully open state as shown in FIG.

When the thumb is released from the operation unit 20, the operation unit 20
Returns to its original state due to its own elasticity,
4 is also pulled back forward and returns to its original form. As described above, in this cap, the lid 30 can be quickly opened by an extremely simple operation of simply pressing the operation unit 20. The pressing operation of the operation unit 20 is very primitive as a movement of a finger, and has good operability.

<Closing Operation> When closing the lid 30 of the cap, the lid 30 is rotated downward against the elastic force of the elastic body 50 and then strongly pressed against the cap body 10. Then, closely together, the closing plug 33 Note Deana 14 engaging projection 35 of the cover 30 is engaged with the engaging projection 23 of the operation unit 20
To fit.
